- To all whom it may concern:

Be it known that I, JosIArr If].' SY1v'roNs, a citizen'of the UnitedStates, residing at Ch cago, in the county of Cook and State ofIllinois, have invented a certain new and useful Improvement in GyratoryCrushers, of

which the following is a specification.

My invention relates to improvements in gyratory crusher-s and has forits Ob]80l3 to provide a new and improved form of such a device.

It is illustrated in the accompanying drawings, wherein- Figure l is aplan view of the preferred form, Fig. 2, an elevation, Flg. 3, a sectionalongthe line 3-3 of Fig. 1, Fig. 4, a section along the line l-A ofFig. 1, Fig, 5, a section along the line 5'-5 of Fig. 3, Fig. 6, a planView of one of the bearing members, Fig. 7, a plan view of a modifiedform of the device, Fig. 8, a section along the line 88 of Fig. 7, Fig.9, a section along the line 9-9 of Fig. 8, Fig. 10, a detail of theeccentric sleeve.

Like parts are indicated by the same letters in all the figures. I

The hopper A which is provided with the outwardly fiarlng upper rim Ahas about its bottom the annular reinforcement A which terminates ateither side in the outwardly projecting lugs A carrying the bearings Aand forming the bottom of the gear casing A which is made up of thelateral walls A and the removable sheets A The rim A has the twooutwardly projecting lugs B located above one end of the lugs A Theshafts C which are mounted at one end in the lugs A and held at theother end in the lugs B by means of the screw threaded 1plug areinclosed within the eccentric s eeves C which are in slidable engagementat their top with the under side of the lugs B and at the bottom aremounted upon the angular rings C, C upon the lugs A and are driven bythe miter gear C in engagement with the gears C upon the shaft C whichin turn is driven from any suitable source of power by the pulley C Thecross sha d frame D is provided with the oppose arms D D which terminateat either end in thesleeves D within which rotate the eccentrics C Thesleeves D are provided near the bottom with the annular flanges D ridingupon the bearing members 11) which in turn are mounted upon the bearingmembers which form a part of the closures for the ear-casing A? and isprovided with the kmfeiedge D in contact with the under surface of theflange D to prevent the introduction pf dust and grit into the gearcasing. The frame D has at top and bottom the laterally projecting armsE, E overhanging and underlying respectively the hopper A and carryingthe shaft E held rigid therein by means of the keys E The hopper A isprovided with the lining plates G having the backing G and surrounds theconical corrugated crushing cone G which is slidably mounted upon theshaft E being held in adjustable position by the screw G the head G ofwhich rests upon the flange G of the bushing G which surrounds the shaftE and rests upon the arm E The collar Gr surrounds the shaft E andis-interposed between the top of the cone G and the under side of thearm E to limit the upward excursion of the crushing cone.

The piping H leads from the oil tank not shown to the top of theeccentric C and permits an oil circulation therethrough from the gearcasing A back to the tank by means of the piping H The screw threadedring H in the top of the sleeve 1) being provided with the laterallyextending flange H having the knife edge H in engagement with the underside of the lug B completes the closure, thus permitting a dust proofoil tight casing, within which operate all the drivin parts of'themachine.

In t e modification illustrated in Figs. 7, 8, 9 and 10, thediametrically opposed lugs K are substituted for the lugs B as an uppersupport for the shaft 0, the' eccentric C being inclosed within thesleeve K which is rovided with the upwardly extending arms at the topand laterally extending arms K at the bottom having the downwardlyexunison thus giving each of the sleeves the same gyratory motion, whichmotion is in turn transmitted to the crushing head.

In the modified form of my device I provide a hopper, crushing head anddriving mechanism in which the driving mechanism takes the form of twoeccentric sleeves located diametrically, opposed across the crusher anddriving yokes, which in turn carry and drive the crushing head.

In my crushing machine when the driving shaft is operated the twoeccentric sleeves .are given a simultaneous motion inunison one with theother and the gyratory excursion of all the parts of the mechanism whichare mounted upon and driven by these eccentrics will, of course, beconstant. It will be evident, however, that it is essential that thegear ratios of the driving gears and driven gears in each case must bethe same. When this is true I am enabled to provide a crushing machinehaving a crushing head within the hopper and driving means outside ofthe hopper but upon the same level. I thus retain the advantage ofhaving a low lift, light weight'crushercapable 'of doing the same workheretofore done by the crushers in which the crushing head was mountedupon a swinging shaft.

I claim:

1. A crushing machine comprising a hopper, a gyratory crusher headtherein, and

means outside of and out of line with the hopper for giving the crusherhead a gyratory movement of constant amplitude at all points therealong,said means including a plurality of eccentric cylinders.
